Units and markup options
To use the Units and Markup measurement tools, select the 3D Measurement Tool, and then right-click inside the
model.
Define Model Units Select to change the measurement units.
Enable Coordinate Display Displays or hides the coordinates of the mouse pointer location in the Measurement Info
Window.
Change Markup Label Type the text that you want to appear with the measurement, both in the 3D model area and in
the Comments panel. (Not available if Measurement Markup is not selected.)
Disable Measurement Markup Select when you want to take measurements in a model, but not add them to the
document. The measurements are only visible while the current measurement is active. If you start another
measurement or change tools, the markup disappears.
Don’t Snap To 3D Content Disables the ability to snap the insertion point to a likely target. Select this option to
improve performance when you are working with a large model. Return to Snap To 3D Content to ensure precise
measurement in 3D objects.
